IMPROVEMENT IN STEAM-CYLINDER LUBRICATORS.

Specification forming part of Letters Patent No. 208,931, dated October15, 1878; application filed April 2, 1878.

To all whom it may concern Be it known that I, NICHOLAS SEIBERT, of

San Francisco, in the State of California, have invented a new andImproved Method of Feeding a Lubricant to Steam-Cylinders; and I herebydeclare the following to be a full, clear, and exact descriptionthereof, reference being had to the accompanying drawing, making a partof this specification, which represents a perspective view of thedevices to carry out my method of feeding the 1ubri cant.

The object of my invention is to provide a means of regularly feeding alubricant to the cylinders and other parts of a steam-engine; and itconsists in utilizing, through suitable devices, the impulse of the pumpinjector or inspirator at each pulsation to throw a given quantity ofoil, to be regulated by suitable cocks, into the steam-chest tolubricate the valves and piston.

In order that thoseskilled in the art may make and use my invention, Iwill proceed to describe the exact manner in which I have carried itout.

In the said drawing, A represents a steamboiler provided with the usualsteam-dome B and steam-pipe C, conveying the steam to the steanrchest 1)over the cylinder E.

The usual pump or other water-supplying device F is connected to thewater-space of the boiler by pipe (1, provided with the checkvalve to.Between the pump and check-valve a, I tap pipe to and insert a pipe,bythe other end of which enters the bottom of acup or tank, G,containing oil or other lubricant. On pipe 0, between pipe at and theoil cup, I locate a check-valve, d, a stop-valve, c, and between them anair-chamber, f.

Passing from-the top of the oil-cup into the steam-pipe, above itsjuncture with the steanr chest, is an oil-supply pipe, 71, provided witha check-valve, 2', and a regulation feed-valve, I. The bottom oftheoil-cup is supplied with a cook or waste-valve, I, to withdraw thewater when all the oil is out of the cup, and a suitable removable capis constructed on the top of the cup, which allows the introduction of anew supply of oil.

The operation is as follows: The oil-tank is filled with oil. WVhen thepump injector or inspirator is put in motion to feed the boiler withwater, the water will be forced into pipe b, and the check-valve awillhold it, and at the same time the air in chamber f is compressed by thewater. Then open valves 0 and I, and the pressure from chamber f willforce a portion of the water into tankG, and the same amount of oil outof the oil-tank through pipe h, and into thesteam-pipe, where it issprayed, and enters the valve-chest and cylinder commingled with thesteam. The steampressure through pipe h'being at an equilibrium, thepressure stored in air-chamber f, by means of the back-pressure in pipea, caused by the weight of check-valve a, or by the momentum of waterbeing forced into pipe (0 by injector or inspirator, will overcome thatequilibrium in favor of pipe h, and force the oil through pipe h againstthe pressure of steam into steam-pipe 0.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The improved method of feeding lubricants to steam-cylinders,consisting in feeding the lubricant through the means of the pulsationof the water-feeding device forthe boiler.

2. Boiler A, cylinder E, steam-chest 1), pump F, and feed-pipe a, incombination with oil-tank G, pipe I), provided with valves 0 (I andair-chamber f, and pipe h, provided with valves 5 Z, all constructed andoperated substantially as set forth.

NICHOLAS SEIBERT.
